TOOL FOR POSITIONING A STUD 0N A SILL Filed April 23, 1949 INVENTOR. Fr ed Rienecker ATTORNEY Patented Nov. 20, 1 951 .UNITED STATES-PATENT OFFICE Fred Rienecker, San Francisco, Calif.

Application April 23, 1949, Serial No. 89,217

The present invention relates to improvements in a tool for positioning a stud on a sill, and its principal object is to provide a tool of the character described which greatly facilitates the placing of studs in the erection of a frame building.

In conventional building operations the studs are placed on the sill in spaced relation, the position of each stud being usually indicated by pencil lines drawn across the sill.

The studs are secured to the sill by toe-nailing, and the latter operation tends to crowd the stud away from the pencil line with respect to which it has been positioned.

It is customary at the present time for the carpenter to place his foot against'the left side of the stud when toe-nailing on the right side, but this procedure is not always satisfactory since it causes the carpenter to assume an awkward position, and usually does not prevent the shifting of the stud under the blows of the hammer.

In the present invention it is 'proposed'to provide a simple aid in holding the stud during toenailing operations, the aid comprising in its general features a flat plate having a straight front edge adapted for lining up with the pencil marks, a flange adapted for placing against the side of the sill so as to bring the front edge into the '1 Claims. (Cl. 145-1) proper rectangular position with respect to the sill, a number of teeth projecting downwardly.

from the plate and adapted to be hammered into the sill surface, and an upwardly inclined section at the rear of the plate which causes the teeth to release their hold on the sill when struck upon with a hammer.

Further objects and advantages of my invention will appear as the specification proceeds, and the novel features of my invention will be fully defined in the claims attached hereto.

The preferred form of my invention is illustrated in the accompanying drawing, in which Figure 1 shows a top plan view of my tool in proper position with respect to a sill and astud, and

Figure 2, a side view of the same assembly.

While I have shown only the preferred form of my invention, I wish to have it understood that various changes and modifications may be made within the scope of the claims attached hereto without departing from the spirit of the invention.

Referring to the drawing in detail, my tool I is shown as applied to a sill 2 of a frame building to aid in the positioning of the stud 3.

The tool comprises a preferably rectangular 2 flat plate 4 of a width corresponding substantially to that of the sill and of a length suited f0 its purposes.

The plate has a straight front edge 5 and is preferably rectangular in form. The rear section 6 of the plate is bent as at I to form an acute angle with the sill. The front portion 8 of the plate may also have aslight upward bend as at 9 to slightly lift the front edge 5 with respect to the sill as shown. This feature insures a better anchorage for the stud, particularly where the bottom edge of the latter is frayed, and allows a somewhat thinner plate to be used than would otherwise be feasible.

Theplate 4 has a flange l0 depending from a side edge thereof, the flange being adapted for placing against the edge of the sill and being arranged at a right angle to the front edge 5 so as to bring the latter into the proper transverse position with respect to the sill.

The front end of the flange IE] projects forward beyond the front edge 5 of the plate to form an extension II, and the upper edge 12 of this-extension projects above the surface of the I sill when the tool is properly positioned.

The plate 4 has a number of teeth l3 projecting downwardly therefrom by means of which the plate may be secured upon the sill. The teeth are preferably struck out of the plate material as shown and are preferably filed down as at M to provide chisel points adapted to cut across the grain of the sill.

For practical reasons it is very desirable that the tool be made of comparatively light-weight I material because this allows the teeth to be struck out in the manner shown. On the other hand the front edge should rise sufficiently high to form an effective abutment for the stud, and for that reason I raise the front edge by bending the front section at 9 as shown.

The manner of using my device will be readily understood from the foregoing description. Assuming that a pencil mark has been drawn to indicate the position of the stud, the carpenter pushes the flange 10 up against the edge of the sill and then brings the front edge 5 into alinement with the pencil marks, whereupon he drives the teeth l3 into the sill to hold the tool in place. The stud is then pushed up against the front edge 5 and the projecting flange portion l2, whereupon toe-nails may be applied to the free edge of the stud for securing the same upon the sill, eliminating all chance that the stud might move from its correct position during toe-nailing operations. For releasing the tool the carpenter merely strikes the rear section 6 with his hammer which causes the tool to pivot about the fulcrum 1 and causes the teeth to disengage from the sill.

It will be noted that the tool is very simple in construction, has no moving parts and can be readily made out of a single piece of sheet material.
